by Haefely Hipotronics 

Catalog ID: 4762 Range Extender, 400A

Capacitance and Tan Delta / Power Factor

More Information


This electronically controlled current transformer is specifically designed for current range extension in capacitance measurements. It has divider ranges of 1:10 and 1:100.The special transformer is accommodated inside a portable casing with all terminals on the top panel.

  • Current Ratio 1.10, 1:100
  • Max. primary current 40 A, 400 A
  • Min. primary current 10 mA, 100 mA

  • Especially suitable for range extension to measurement of high capacitances
  • Very wideoperating current range Imax: Imin = 4000:1
  • Very accurate measurement, even with heavy burdens
  • Negligible transformer error eliminates calculation of measured C and tan delta correction factors
